Description:
A tool for the preparation and enrichment of health datasets for analysis (Toner et al. (2023) ). Provides functionality for assessing data quality and for improving the reliability and machine interpretability of a dataset. 'eHDPrep' also enables semantic enrichment of a dataset where metavariables are discovered from the relationships between input variables determined from user-provided ontologies.
